how to name the images

I was looking for the right name to name the preview image that shows on the homepage of themeforest. I have a thumbnail.jpg and a themepreview.jpg image in the preview_images.zip file that contains the images of the pages. Is this correct?

You can always read the instructions .

Create your Screenshots ZIP : For each item you must include a ZIP file of screenshots depicting the template, for use as a preview of the file before download. Screenshots should be JPGs, should be no larger than 1200px in width, but can be any height. You can have up to 10 screenshots of the item, and each screenshot may have a description attached. Here’s how you set up the file: Name each screenshot in sequence as number_Title.jpg. E.g. 01_Homepage.jpg, 02_Generalpage.jpg. Create a .TXT file containing a few lines of descriptive text, with the same name as the screenshot. E.g. 01_Homepage.txt, 02_Generalpage.txt. ZIP up the JPGs and TXTs together into a single ZIP file.

I have read it. but it was missed in my previous upload. So I thought that maybe it needed a special name that I was missing. So I was just checking

If it isn’t in the instuctions, you probably good with any kind of name. Upload and cross your finger that it’ll be accepted. That’s what I do, when doing a first upload into a new market.
