Gallery JPEGs incorrectly sized

Hello,
I feel that I may have inadvertently reconfigured a setting that is causing an issue with my image renditions. I have been starting to populate my galleries with new images but compared with earlier images they are about 50% smaller. To keep a constant I have even duplicated and renamed the earlier images keeping the exact JPEG settings and their size is smaller when compared to the original import.
Any help would be appreciated!

Make sure your image rendition sizes in your album template is what you need it to be.

If you’re using Lightroom Publisher, the images will be sized to the template settings before being uploaded to your site.
If you’re using Backlight Publisher, the images are resized by Backligt. Make sure you’re uploading images that are at least as large as the album template calls for

Thanks Rod, looks like I decreased the Photos Width and Height after the initial uploads.
