I have a few jpg images and I need to have a transparent background. I will add these images in a web page and I need to see just the main element of the image and the web page beneath.
Does anyone know how to transform an image in one with a transparent background?
I have GIMP.
Thanks
You'll want to use a PNG as your output, JPEG images can't contain transparency, and GIF's only have binary transparency, ie full on or full off. Haven't used GIMP in a (long) while, but you can try the tutorial here: Transparent PNG

I got this aerial image of a warehouse from Google Map, and I'd like to analyze the characteristics of the building inside the image. How can I find the approximate building footprint?
I learned some functions for matlab image processing. But I'm still a newbie for image processing. I'll be very appreciated if anyone can help me.
Or is it easier to figure out the area using the roadmap image below?
Import the roadmap image in Matlab, convert in in an 8bit greyscale image and use the following binarization.
BW = imbinarize(I,'adaptive','Sensitivity',0.68);
figure, imshow(BW,[0,1])
From Here you can either use regionprops (link) or extract lines using a Hough transform.

I need to create splash screen for my mobile application and I want to use an image like the one I have attached with this question but with different color for splash screen.I guess this is a gradient but really don't know any idea how to create this type of gradient image with different color.Please help me providing any link or tutorial.
Please take a look at
http://docs.gimp.org/2.2/en/gimp-tool-blend.html
http://www.youtube.com/watch?v=wjuCM-UTXaQ
for some gradient tutorials.
If you want the same image, with a different color, then just try changing the hue of your image like this

As the title states.
This is happening to me on Windows with images that have a transparent background.
Is there a way to avoid this on copy - paste?
Ok, well what I forgot to mention is that after I copy pasted the image, I also resized it using paint expecting paint to preserve transparency.
But it appears Paint doesn't do that.

I have a transparent PNG Image. I want to add it as watermark for this video recording software. But the problem is, software requires jpeg image as a watermark. When I converted that image to JPEG(using Pixle Editor) it lost its transparency and does no look good in video.
How do I convert Tranparent PNG to Tranparent JPEG?
It doesnt matter how or which tool.
EDIT:
How to convert transparent PNG to transparent GIF?
JPEG format does not allow transparency. It does not include an alpha channel. So the answer is : there is no such thing as a transparent JPEG image. Transparency is possible using PNG, GIF or vector based formats, dunno if you can manage the watermark in those?

I'd like to edit an animated gif to change its background from white to #f5f5f5:
Photoshop can import it and shows as layers, but saves only the first frame. Are there any editors, preferably online tools that allows it?
Many thanks for your help!
Graphics Gale is used by a lot of pixel art guys, it is rather good for working with animated GIFs.
