Ok, let me fully explain this so that it is clear. We are a graphic design firm, that needs flawless graphics to be displayed on our website...
The album thumbnails, image thumbnails, and final image needs to be FLAWLESS. Our images are always a maximum of 640 width or 640 height, and in .png format for lossless. Our problem is this:
Even when we upload our image which is say 450 width x 640 height or another image which is 640 width x 325 height, we can ALWAYS see dithering (specs and haziness in our images). We can not have this happening. If we upload a .png image within our dimensions, we do not want the image resized ever, not at all. We know the image will be stored by the script (module), but we do not want it resized. I understand the script will resize it to the thumbnail size (for album covers, and thumbnails) that we specify, and that is ok, but we would prefer that even that is at the MAXIMUM visual setting we can get, and zero dithering.
We have tested outputting here, even with a problem as basic at Paint.net, and our outputs look flawless. And yet...
On our Gallery page, when we upload .png image, you can see a severe quality loss. Does ANYONE know what we can do about this? Can we manually upload the images via FTP a folder or anything. These images are critical for us, and can not have the lines, bands, dots, or other issues that we are seeing with this module. How do we tell this script to NOT touch the main image that we are uploading?
We always upload flawless png images, and on a rare occasion a .jpg at the highest level of compression possible, for the highest quality. I would say .png images about 98% of the time.
What can we do here. |

Is your site online so I can view this? If it's within dimensions, it shouldn't be resized at all (support@ventrian.com).
PNG resizing is a little more complicated, but if you don't need resizing, it shouldn't be a problem, please provide examples. |

First, ensure you have un-ticked the "Resize Photo" option in the module settings. This tells the module to leave your full size images alone, but you then of course have to have them resized prior to upload.
Second, as far as I know (and I'm one who instigated the quality image processing for Simple Gallery), the quality function is not meant for converting PNG images - and it is highly likely that it is making a mess of them. If you want the module to resize your large images, upload quality JPGs instead.
Note that this is the only DNN module available that makes use of a high quality image handler. Your only other option will be to create your pages using Text/HTML modules and manually-inserted images. This may very well be a good option for a design firm as it offers the best possible presentation.
Scott might have something further to add to this., so wait until he's seen the post as well.

I am going to add one design, which is a business card design. I resize all my images prior to uploading, and always make them png images. My maximum image width and height setting in the module setup is 800, but I always stay at 640, no where near the limit.
http://www.pixelmatters.biz/main/Portfolio/tabid/54/Default.aspx is the address to our photo album. I uploaded the Spoken Word Business Card design we did, and uploaded the image at 640 height maxmimum.
When we view the image, we can see definitive dithering below the name Joshua, to us, its clearly seen. Its a set of unfocused dots and hazyness below the word Joshua. This should not be, as the original is razor sharp.
We had set the module for maximum clarity, and had turned off ALL resize settings. And yet, still, this issue. We simply want to be able to upload images that we have already resized, in png lossless format, and have them flawless.
Please post any feedback, as we need to resolve this issue if we can. Thanks for your time everyone. |

Hmm, to generate that thumbnail, it does need to dynamically resize based on the original image (regardless of the resize setting). Your original image is not resized based on the image when you click to view it, so that part is true. The thumbnail is the issue correct?
I could take a look at PNG high quality settings, but without you specifying a thumbnail image, a resize has to take place. The high quality settings are based around jpg/gif at the moment. |

The thumbnails are fine, I know they have a slight issue because they need to be resized.
But my full size images, those are a problem. I already resized them, and do not want them resized, I do not want them reoutputted, they are somehow losing quality, and there is no reason for them to be resized.
I always resize my own images to either 640 width max or 640 height max, as long as my height or width do not exceed 640.
So now, I upload an image that I made, say its 640 width x 480 height, and its a png image. I go to view it, BOOM, hazy or a little dithering. I can't have that, people judge our work on what they see.
How can I fix this. |

Ahh, I see it now.
Can you send me an original photo for testing purposes? (support@ventrian.com), or provide download link. |

| Hmm, did you change image dimensions after uploading? The image you are seeing in the detail is the image handler, this is invoked if the maximum dimensions of the photo are different to the photo uploaded. |

| No, I never change any dimensions that I know of. I simply upload an image, and let it go. I think I have everything set correctly also, to where it does not resize. I will email the image I use for testing purposes. |

| Max quality please :) I wish there was a flawless setting which would force the system to not touch the images with the exception of making the album and image thumbnails. |

| That's what don't resize should do, but I don't think its doing it, it's probably running it through the image algorithm and not changing the width/height. |

Weird. Well, this is your script Scott, if you cant do it, no one else can. I wish I could just say upload and store with no resize, and generate thumbnails and album thumbs at max image quality.
I am quite sure I make it sound easier then it is, but surely there is a way to make this thing not touch an image, merely store it. |

| Scott are you looking for a setting here or are you adding a whole new addition for a png image? |

No changes for settings, when it's marked to not resize, it shouldn't touch the image. Unfortunately, it looks like it is doing it, so I'm working on a fix at the moment.
I checked the staff profiles and saw that you had a DC guy, nice! |
