Why does WP reduce the quality of my header img?

When I first uploaded my custom header it was about 60k .png image. After the crop it got turned into a .jpg file at about 15k. I can understand that it may have something to do with bandwidth consumption, but the quality is horrible.

Next, I took my original picture and reduced it to about 15k, but when I uploaded that one it still got degraded. Why is this happening? And whiy do I have to crop an image that is already 750×140 pix (Contempt theme)?

i.. don’t know.
it doesn’t seem to be a size issue. mine is 99.79 KB
i am using a .png, though, which is harder to compress. try saving as a png before uploading.

I have a custom header, created using Fireworks, but I exported it from Fireworks as a jpeg first, then uploaded this to WP. Seems to work fine and WP only took a few 3KBs off me! :)

Well, the first image uploaded was a png image and it got turned into a jpg of REALLY low quality. No idea why. it may have something to do with the theme.

i might have to submit a feedback tomorrow.

sunburntkamel, your header is a jpg too. guess wp auto-converts to jpg. dunno why yours is good.
are you a paying member by any chance?

It tried to crop mine as well using the Sapphire theme even though it was the correct size. Never heard anything on the issue so I just added it into the CSS and moved on.

We recently updated the custom header code due to complaints about file sizes increasing. The new code generates JPEG files at 75% quality.

drmike, when I upoaded my header I had to drag the crop tool across my image, so that it was effectively cropping the whole image, or rather none of it.

What I mean is there was no option to miss out the cropping part of the upload procedure.

That’s the issue I raised as well.

Something I mean to do with the cropper is test the image size and accept it as-is if it matches the theme’s header image size. Good things come to those who wait, right? Expect it in the next few days.

Does that mean that it won’t reduce the quality of the image to 75%, or it will just skip the crop part?

Can I at least link to an off site image hosted on sites as photobucket or flickr? that would be very acceptable on my side.

I just made a change to the custom header resizer which should make the images *much* higher quality than they used to be. Try it out and see what you think.

Should I re-upload (if that’s a word!) my header image then?
