I have just purchased Simple Image gallery Pro and I must say I am impressed at how quickly I got a number of galleries working. however I do have a number of small issues, as follows:

1. Number of images per row in thumbnail view is too wide for the page and if I reduce the size of the thumbnail it just seems to add another one to the row.

2. If I go to using a single Thumbnail it always puts it to the left of the page no matter what I do to move it to the right.

3. I want to use the actual size of the image with the single thumbnail option but ti doesn't resize it any bigger it just puts a border around it.

1. You need to modify your template css.

3. You can set bigger dimensions for thumbnails via SIG PRO plugin parameters.
