In less than 3yrs I filled WordPress’ 3GB of free memory allotment. I’m guessing that’s a bit over 1000 images. I could have fit a lot more photos in that space if I had resized each one to best fit the blog, but I also upload my pics to Flickr and I like having the highest resolution for that site. I’m a big believer in lots of photos for a blog. I have a hard time reading blogs that are mostly text.
I paid for another 5GB of hard drive space so I should be good for another 3-4yrs…=-)
