All operations you can do only with images selected in the List of images.
If there is a necessity in two or more identical frames, select wanted image and use menu operation Image / Operations / Duplicate or click the toolbar button of Standard Toolbar. New frame will have the same attributes as the current frame.
You can create a new image consisting of two and more images. For example, one image can be used as a background for other images placed on this background in different places. To merge all images checked in the List of images use menu operation Image / Operations / Merge or click the toolbar button of Standard Toolbar. If two frames inside GIF have local palettes with different sets of 256 colors then the palette of merged frame will be converted to some new 256- colored palette. As a result of this operation you can get changed colors in merged frame.
Crop.Sometimes there is a necessity to use some rectangle part of an image as a new image. It can be made by selecting a necessary fragment with the help of menu operations Image / Operations / Crop or by click on the toolbar button of Standard Toolbar.
