Go to the Materials Palette. Under the rectangles for foreground and background colors, are three icons. The icon to the left has a little triangle in its lower right corner. Under the foreground color patch, click on that triangle. The middle icon, below the black circle, is the gradient icon. | . . . . . . . . . | <--- doing that, be sure you haven't clicked on the wrong icon because clicking on the icon in the middle will cause patterns to display and you won't be able to get to your gradients while the Materials Palette is showing patterns or textures or whatever. |
Click on that
gradient icon. Now the rectangle for the foreground color shows one of your gradients. Click on it. That opens the Material Properties dialog box. The gradient you clicked on is now larger, with its name above it, and a frame around it. In the frame, on the right side of the gradient, is a downward-pointing triangle. Click on that, and all your gradients will appear as thumbnails.
If they do not, the gradients-display should appear anyway; at the top, there is "Category:" in front of a box with "all," or "duotones," or "gradients" or "landscapes" or "metallic" (these are the ones in PSPX; yours may differ). Click on the downward arrow (
v) next to the textbox to the right of "Category," and choose "all." That should let you see thumbnails for all your gradients.
If it doesn't, look to the right of the
v: the 2nd button has a picture of folders on it and has the tooltip "file locations" when you put your pointer on the button. Click that button. Now you have the File Locations dialog box displayed. Under "file types" (left panel) "Gradients" should be highlighted.
If it isn't, click on it to highlight it. That should cause the right-hand panel to be "Gradient File folders," with the locations of your gradients files. Use that dialog-box panel to let PSP know where your gradients are. I.e., use "..." and "add" and "remove" and "
^" and "
v" and the checkboxes under Folder Options.
If you don't know where you put your gradients folder, use Windows Explorer Search to find the folders named "gradients," or look in My Recent Documents to see where they were last time you used them.
If the foregoing does not relate to your question because all your palettes have disappeared (though you say you want "it" back, not "all the palettes"), make the main window of PSP smaller so that a bit of your desktop appears (or use Windows' "Show Desktop" icon if you can find it), and right-click on an empty place, choose Properties, open the "Settings" tab, look for the "Screen resolution" panel, make the resolution very large, do "OK" or "Apply," and your PSP main window will become smaller, and the lost palettes will appear where you could not see them at normal resolution. Move them toward the center, and then make your screen resolution what it was before you increased the resolution.
