How to Make a Clash With Opacity in GIMP
You can use the graphics editor GIMP to merge multiple images, adjusting the opacity of each so the pictures can clash according to your preferences. For example, you can make one picture more transparent than another or lay out the pictures to be overlapped at a particular angle. Using online software where you upload two pictures, and the resulting mashup allows for no customization, may or may not give you a desirable end-product. Using GIMP, on the other hand, gives you complete control as to how the pictures will come together and what opacity will be assigned to each.

Launch GIMP, and open the file you want to use as your background image by clicking on "File" and "Open." Locate the graphic within your documents, clicking on the file itself to highlight it, then clicking on "Open" to finalize the step. A workbook will appear with your image as the background.

Insert the second image you want to merge with the background by clicking on "File," and "Open As Layer." Locate this image within your documents, and press "Open." Make sure this layer has a transparency channel by clicking on "Layer," "Transparency" and "Add Alpha Channel." If the text "Add Alpha Channel" is grayed-out, making it impossible to click on the entry, the layer is already set for you to edit.

Use the "Move Tool" in the main toolbox to re-position your second image within the workbook. Click on the icon and then double-click and drag the image to where you want it to rest. You can also use the keyboard arrow keys to make step-by-step adjustments.

Open the Layers toolbar by clicking on "Windows," "Dockable Dialogs" and "Layers." The toolbar will appear, showing you a thumbnail of each layer that exists in your workbook. The layer that is currently active will be shown by the corresponding thumbnail being highlighted.
-
5
Change the opacity of the active layer by using the scrollbar to the right of "Opacity" at the top of the Layers toolbar. An opacity of "100%" means the layer is completely opaque, while an opacity of "0%" means the layer is completely invisible. Adjust the scrollbar until your pictures clash as you want them to.

6
Use the "Eraser Tool" to entirely remove unwanted sections of the top layer. Click on the icon in the main toolbox and double-click and drag your cursor over the unwanted areas. You can use a brush type of "Circle Fuzzy" to create soft edges where your pictures merge as opposed to a solid, hard line.

Tips & Warnings
You can continue to insert more images to clash together by clicking on "File" and "Open As Layer."
Because you have created a multi-layer workbook, when you try to save the file using a picture extension such as ".jpg" or ".png," you will be required to flatten the image before the saving process will complete.
