Hi there, I have this very basic problem. Event Gallery is fantastic but I don't understand why the real photos look damaged at the bottom. See sample in attachment. The original images are fine, the thumbnails look fine as well but most of the full screen photos look damaged. I thought it might be a problem with Safari but I see the same problem in Firefox as well. Any idea?
Thanks in advance.

Seems like the delivered jpg is damaged somehow. What do you mean with "real photos"? Is it the image which loads in the light box?

Can you provide a link to your site please?

Thanks Sven for your super fast reply. The website is on-line but not public yet. I will send you the link and login data by mail. Anyway, you'll see that I'm using the beta release, but this is only because I had the same problem with the v3.2 and I hope the new one could solve the problem. I thought it might be a setup problem and tried different combination on the image tab but nothing changed. Sorry for the trouble.

Strange. There is a "Clear Cache" button in the top menu of the overview page of Event Gallery. Please use it. Or empty the Joomla /cache folder.

Here is an example url which seems to deliver an invalid image: http://www.sat123.it/components/com_eventgallery/helpers/image.php?option=com_eventgallery&mode=crop&width=576&view=resizeimage&folder=Journeys&file=london2011__120.JPG

Maybe this fixes it.

By the way, there is no difference in how the images are rendered between 3.2 and 3.3. But since you're on 3.3 now, please do not downgrade again.

Thank you but I've done that so many times. Cleared Joomla and Event Gallery Cache but nothing... I thought it could be "sharper matrix" which I haven't change and is [[-1,-1,-1][-1,-1,-1],[-1,16,-1],[-1,-1,-1]].
Then I have selected "use original file" - no fallback and no sharpening... and yet nothing. You are my last change. Am I the first one to describe this problem?
And Yes I won't downgrade to 3.2 why should I? It looks great to me and my problem is there as it was before.

The rendering works fine. Otherwise you would get a damaged image every time. As far as I can see the image.php script works if it's call for the first time. If the browser delivers the image from its cache you see the broken image.

Did you turned on the legacy rendering mode? That will not use the image.php script which seems for fix this for now.

I have another idea. You server seems to set the header Transfer-Encoding:chunked. Try to disable this:

I'm nearly sure this will fix the issue.

Thank you so much Sven, you got it right! This is what I have done:
I have changed the default htaccess.txt into .htaccess and added the following lines:

SetEnv downgrade-1.0
RewriteRule . - [E=no-gzip:1]

then I've turned on the system cache into joomla plugin (I don't know if it helped or not).
I've also turn on "mod rewrite" in the global configuration panel, after changing from htaccess.txt to .htaccess which should help anyway for better SEO, but I don't think this is related with the problem.
As you suggested those two instructions in the .htaccess made the difference.

Thank you so much.
Now I've got a fantastic Event Gallery 3.3.
