To fill text with an image in Photoshop, duplicate the background layer, add a new layer between them, fill the new layer with white, add white text on its own layer between the background copy and filled layers, then make the background copy layer a clipping mask for the text layer so the image shows through the text shape.

1. How to fill a word with an image in Photoshop
1. Open your image in Photoshop.
2. Duplicate the layer by selecting Layer > Duplicate Layer. Then create a new
layer by selecting Layer > New > Layer.

2. 3. You will now have three layers, your background, the background copy (from
duplicating it) and a new layer. You need to drag the new layer in between
the two background layers.
4. You now need to fill the new empty layer with white. Do this by selecting Edit
> Fill.

3. 5. A pop up box will appear, make sure the drop down menu is selected to
‘White’ and the opacity is 100%. Click OK.
6. Now add in your text by selecting the Text Tool (‘T’ on the left hand side).
Make sure your text types in white colour.

4. 7. Drag the text layer above Layer 1, and below the duplicated background
layer.
8. Select the duplicated background layer (probably titled ‘Background copy’) –
you will know it’s selected because it’ll be highlighted blue. From the top
menu, select Layer and scroll down to ‘Create Clipping Mask’.
9. Your image should now be sat within the text. Save as a JPEG file.
