Reduced picture size

[Kjell]

Hi!

I'm new to Pixelpost and I've got a problem with Pixelpost 1.6.

When I upload pictures I can see that they got the size I've chosen for them both in /images/ folder and in Admin->Images. But when they are displayed, they are dramatically reduced. The height & width are OK, but the pixelcount is far less than the original and it shows in the photos.

What do I do wrong?

The biggest problem is not working site :/

What is the quality of the pictures? (On a scale from 0 - 100?)

[Kjell]

The original is roughly 250KB, the displayed one is 40KB, on a scale from 0 - 100 that should be less than 20.

[Dennis]

yeah.. you got that right. Let me clarify my question.

Pixelpost doesn't resize the pictures by default. This has to be done by an addon of some sort. That addon should have a quality setting. What is the setting of the quality setting?

Furthermore, KB does not have anything to do with picture quality. Things like DPI are far more important then size.

[Kjell]

DPI, I don't know. I thought that DPI and height and width would make up the .jpg's file size. But I can see the photos displayed in PixelPost are degraded compared to the photos before I upload them even though they have the same height and width.

So I removed everything in the addon directory and uploaded a "untouched" picture-file. Original file size 2,5MB, displayed file-size 0.5 MB. Height and width are the same.

I'm puzzled. If PixelPost doesn't do anything, what am I doing wrong?

Are you resizing the images locally, then uploading them, or are you using an addon to resize the images in Pixelpost?

Also, go to the General Info page in your PP admin, and copy/paste the info under "host information" section for the version of GD-lib your server runs so we can see if there's an issue with GD-lib that could be causing this. That's the only other thing I can think of that would affect your image quality that is server-side.

Your images look fine to me. Have you checked the image itself, directly out of the images directory, rather than embedded in your template? The reason I ask is that you're using a fade in script that has some well documented problems when run in IE.

[Kjell]

First of all. Thank you for helping.

To dhdesign:

Yes, I am resizing my images locally and I have removed everything in my /addon/ directory. Now it's completly empty.

I've copied the information from Host Information below

GD-lib bundled (2.0.28 compatible) with JPEG support

To dakwegmo:

I've changed back to my original template and deleted the last picture I uploaded. (It was too large.) And I displayed some of the images directly from the /images/ directory. The jpegs' file sizes were like they were when I uploaded them. And the pictures were definetly better looking than displayed on the website.

[dakwegmo]

Are you using this "addon" to watermark your images: http://www.pixelpost.org/v1/index.php?x=downloads&details=97

If so, that could be the culprit. If you have a 72 dpi png watermark, and your jpeg is 300 dpi, when you use that script to overlay the 72dpi image over the 300 dpi image, there will be a noticeable loss in quality.

[Kjell]

Bingo! Of course, you're right! Thank you.

I've totally forgotten about that addon! I missed it, because it's in the /admin/ folder and in addition I've hacked the .htaccess file in /images/. But dowloading the pictures after removing the watermark, I realize that my picture files probably may be too large anyway.

Thank you all for helping out, and dakwegmo, you got a sharp eye!
