How to add new pics to my webshots collection

[sandeepkochhar]

Hi
I have a webshots collection of 400 MB. Recently I got another 250 MB from my friend. Now the problem is that unlike previous format which was *.wbc or *.wb, the new format is *.wb1 doesn't allow to add new files directly. I tried to copy-paste but it resulted in a hotchpotch and while some new pics were added many of the previous pics were replaced as they were having same names. Even tried renaming new collection but to no avail.
Can anybody help?
Thanks in advance

did you contact webshots about ur prob?

Nope, that is not my problem in particular. Anybody who wants to add new data via other source except from webshots website will face such problem. I think they have made the new format in the way so that people couldn't exchange their webshots data among themselves and they have to visit Webshots site.
If that is the case I don't think that Webshots people will help me out. Have anybody a workaround for that.
