Some tools that I made and use often.
Image - Watermarking ||
My IP LookUp||
When there is a need to enforce copyright of an image, I watermark an image with text. It won't prevent a user from saving/downloading the picture, but the image will always carry the watermark of the originating website. The watermark cannot be removed.
An image can be customised in various ways. For this example, I resize the image into a 300 x 300 pixel image, put a white border of minimum 5 pixel and centre the uploaded image into this image. This is really handy when site administrators don't want to waste time resizing each image to a specific size, before uploading them. It cuts down on all repetitive work and give the site a linear look.
Any image type can be watermarked. To keep things simple I have currently allowed only jpeg files to be uploaded here.
