Digital Photos, Photo Storage, Free Prints, Photo Albums

I was told there are limitations to the Yahoo Photos free storage such as you can only upload 300 photos to an album, and that you can only upload a certain number of photos in a 24 hour period. Beyond that I was informed the storage is still unlimited and free. NOT TRUE. For the past week I’ve received the error “you only have XX MB’s of storage remaining” when I try to upload pictures. Apparently Yahoo photos is touting a feature to their service that is not real. This is false advertising.
If somone can answer my question as to why this is happening it would be great. This experience alone has caused me to want to switch photo sharing services, as well as tell all my friends that Yahoo Photos is not what it claims to be.
