I usually change the previews and/or change the action file, that's why i don't like my photoshop actions be uploaded in other places. Uploading the preview is fine, BUT with a link to the orginal download, thank you.
I work for a school and was interested in maybe using some of the actions to connect with our current students and alums who are into Instagram (or photography in general), so it would not be for personal use, but not really for commercial either. If any of my photos were published, it would be within our community (website, newsletter, alum magazine). Would my use be ok with you? Thank you!
