Welcome to Pixalo. To be honest the auto resize functions of most sites cause quite a drop in image quality. It's always best to use the like of Photoshop to resize shots to ensure maximum image quality is maintained.

If you do have shots on FLICKr, you can use the URL load facility of gallery to upload them there, or you can post image directly in the forum threads using the IMG icon on the rply box (icon of mountain)
