Batch image resize

Hi

I have an excel spreadsheet which I am currently preparing to add to my products on my page.

One question I have is, when I add products manually, the .net script resizes the images and appends and _ and the image width to the end of the file (before the extension)

I would like to know, if anyone could help me in doing this ready to add to my spreadsheet....I do not wish to add the images manually to my page as I have more than 1200 products.

I have photoshop and can batch, but unsure about the appending at the end of the file name, as when I try, it just overwrites the first image it created over and over again.

I hope this makes sense to someone, and they can assist.

I'm using Photoshop CS6.

Thanks

I have now found the problem, was due to each image starting with a number then dot.

I have removed this, and all is ok

Thanks
