Dear friends. Please suggest me what to do, i have an e-commerce website of 300 pages and having more than 100 product images on all pages, should i put any robots.text file for image folder or what is the best way, i want to do SEO for my web site. Thanak You.
Only you can answer this. The question you need to ask yourself is do you want to stop your images being indexed in Google images? If so, then you need a robots.txt file. Otherwise, it's not necessary (except maybe to specify the sitemap, although it's a bit redundant really).
Thnak you so much friends for your kind infomation, it would have been more helpful if you would have elaborated it more!!!!!
Please go to 5starwatchesonline.com and elaborate it more for image optimization, and what i should do with images on my site,i will be really obliged to you Thank you so much !!
I still don't exactly get what you want. I guess optimising for Google images, which has nothing to do with robots.txt. Well, what I notice immediately is your images don't have meaningful names. For example, you use "07.jpg" instead of "black-dice-unisex-07.jpg" (having a number isn't a problem and can maybe even help you keep them organised, as long as the numbering system has a meaning to you).
If you want your images found by search engines add images to robot.txt. When people search images they will come to your website by clicking on those images.
That makes very little sense. One would not list each individual image in robots.txt. However, depending upon your CMS, it might support a sitemap for images. I recommend the OP reads this article (as a starter) and researches microdata/rich snippets further. (This isn't for images optimisation specifically, but will give you a big overall SEO benefit.)
