Portfolio Press Theme – Thumbnail/Image Uploading Issues

I am having a few issues:

1. Images are cropped within the thumbnails so not all of it is visible.

2. One of my thumbnails is a different size than the others, creating spacing issues between other thumbnails. I tried regenerating thumbnails and this did not fix the issue.

3. This may be an issue with WordPress itself, but I get and HTTP error when trying to upload certain images. I spent over an hour on the phone with GoDaddy customer support since WordPress’ support line is a dead end with nobody on the other end. I tried uploading through an FTP client and it still wouldn’t work. He came to the conclusion that it just doesn’t like those particular images for some reason (I tried changing dimensions, resolution, file type, etc to no avail) or it was an issue with my theme of plugins. I disabled my plugins and changed my theme and was able to upload SOME of the images, but others still get an HTTP error (I activated the plugins again and changed the theme back and there seems to be no issue with the images I was able to upload after deactivating the plugins and changing the theme so I don’t think that is the issue) however the color looks off on these images upon upload and on some the color became posterized and all out of whack.

Hope this makes sense. Help ASAP would be appreciated, I need to apply for internships for the Fall semester and I only have a few weeks left. Thanks.
