Why are agents bothering to include photos that can't be seen in their tours and gallery? How does it benefit the viewer and what is the viewers impression of the agent who posts these useless photos? I have several photo editing programs including PhotoExplosion and Adobe Photoshop but I recently came across an online editor that is worth mentioning called Picnik http://www.picnik.com
This is currently a beta program and sign up is free. Since it operates on the web without any downloads, it gets upgrades without you having to do anything. I tried several photos and even some that I thought looked good looked even greater after I ran them through the program. You can also do neat things with the cropping feature including rounding the borders and adding the same color as your website background to fill in the cropped area. Resizing photos includes automatic sizes for YouTube, Google, aviators, etc. You can also save to different formats such as .jpg, bmp, giff, etc.
They don't currently offer any storage albums but that is something being planned in the future. Give it a try, especially if you don't currently have a decent photo editing program since it works equally well on both Windows and Macintosh as well as all browsers including IE, Mozilla, and Safari.
