There's something strange here, when I upload files, multiple or solo, I find error in the jpg format, it appears as a broken picture and can't be seen, but if the format is png it shows normal, no problem here.
I tried with different names, sizes, etc, etc, etc and can't make it work.

I tried the site in a local (mamp) and in the server and it's the same for both

Any ideas about why does not support jpg?

Thanks

Here is what it appears.

Also, I can see the files in the folder images/eventgallery/demo/ and they are fine!

Yes! like you said it, in jpg is a blank image, and in png I can see the image

I added the parameter in the url to verify the server and it still not working, so... it's a server configuration problem? any idea how to proceed?

What about the live server? the problem was there too

First of all, THANKS for the quick answers, it's really nice to know how much you care about people using you component! :D

and second, it have the same problem at the end.

I've tried with a lot of sizes of jpg and in all of them I have the same problem
