Obtain more than 100 images using Matlab from Yahoo image database

I attempting to obtain more than 100 images per term using Matlab from Yahoo images. The problem is I only get 50 images per term and even if i set my request to 200, the remaining images will be similar to the first 50 ones. Any one who has experienced or done this before can suggest me something that will allow me to obtain the desirable number of images. Highly appreciate your kind response

Do you get 200 unique images if you do it manually via your browser instead of from a MATLAB script?

@Image Analyst. Yes I do get when I am doing it manually

What's your code to retrieve a singleimage or the whole batch of images?

[KnowledgeSeeker]

It retrieves 50 images only and the remainings are the same as the first ones

I still don't know what your code is. They have not yet released the Crystal Ball Toolbox, so until then you'll have to post your code in the body of the message or use the paper clip icon to attach the m-file. Only then will we be able to know in detail what it does.
