Well, I just love Flickr! I have been using their photo storage service for over a year now to back up my felting photos as well as some of my personal family photos. I have found it to be a great place to network with a large community of people who have all kinds of interests. There is a group there for just about everything, and if you don't find what you want in a group, then you can make your own. Below are a list of a few direct sites and article posts that offer services and tools to go along with your Flickr account. I have found these to be very helpful in using my Flickr photos to the fullest. I hope that you find them to be useful too.
Big Huge Labs has lots of cool tools! I used their mosaic tool to create the image above. Slide allows you to make neat slide shows and more with your Flickr photos and other apps too. Quick Online Tips has an article with a huge list of sites related to Flickr toys, tools, and more. PedagoNet also has a big list of sites for Flickr tools. FlickrTools is another list of sites for more toys and tools.
Although I've been working as a graphic artist in print publications for several years, I am not as savvy when it comes to most things involving anything beyond basic html for web design. I often times rely on great resources that I come across online, and if it is a free service, then that's even better! Recently while updating the gallery page on my website, I came across an easy service for making great slide show presentations at Slide. You can also manipulate your photos there to add funny imagery and dialogue. It is free to sign up and use the service too, but you do have to put up with their logo and links at the bottom of your slide show. I think it is a small price to pay so that I don't have to worry about figuring out the code and other technicalities to do it myself. As I've said before, I'd rather be spending my time felting.
This is not the only website out there that offers slide show rendering. There's also Flash Slideshow Maker. I don't have any experience with this one personally, but the Kansas City Etsy Street Team blog uses it quite often in articles. I'm sure that there are many more options available too if you just do an internet search. I'm always on board for making life a little less technically complicated. And, it is a great way to show off all those wonderful handmade arts and crafts.
