After you are done resizing the image, go to the Layers palette in the lower right-hand corner of your screen. Click on Layers, and this will bring up the dropdown menu. Select Multiply. This will create a multi-layered image, and start blending the two images together. But, you will probably want to blend these two images further since the texture image will be very visible at this stage.
Now, use the Overlay option. This will undoubtedly make your image too bright. So, you need to change the image opacity. To do this, make a copy of your original image, which will be the background image. Then, move the texture layer between the two copies.
To actually change the opacity of a layer, select the top copy. Enter either a number in the opacity box, or use the amount sliders. You can also access the opacity option by going to Layers, and then Layer Style and Blending Options.
You can add additional textures using the above method, but you need to keep adjusting the opacity. Experiment with these steps until you get the desired effect.
