Hi,
I've found a number of bugs in K2 and Image Gallery Pro.

I'm running:
Joomla v. 1.5.15
K2 v.2.2
Simple Image Gallery Pro v.2.0.4.

So these are the first two...

1). When uploading a zip file containing images I noticed a bug in Simple Image Gallery Pro 2.

It seems that images with more than X amount of characters are not displayed, but do appear on the article pages in the form of an empty container but no thumbnail or image.
The containers do have the dimensions of the images. 

 - When Popup engine for image galleries is set to Highslide, thumbnail doesn't work but the poppup does. (images 1,3)
Furthermore, I cannot edit this item anymore, tabs don't work and I can't replace or delete the previous gallery

2). After upgrading to K2 v.2.2 the upload button disappeared on my 'image gallery' tab. (images 2)

In desperate need for some advice :)
