You need to use xyouts to write the string where you want it, or you
could try using a plot,/nodata to create a data coordinate system and add
a title. e.g.
plot, /nodata, fltarr(2), xsty=4, ysty=4, xrange=[0,1], yrange=[0,1], $
title='MY TITLE'
tvscl, image, 0., 0., xsize=1., ysize=1., /data
N.B. this will only work in PS (or any other future device with scalable
pixels).

Use XYOUTS
like this:
XYOUTS, x_coord, y_coord, 'Your title here'
You can add keywords /Device or /Normal ( or /Data, which won't be valid if
you only TVSCL'd, since no data coords were set up)
You can also add an Alignment keyword to tell it to center, left, or right
justify the text about the coordinatde point. Use Alignment=0 for left, =1
for right, =0.5 for center.
So, you can do something like this
TVSCL, image
XYOUTS, image_width / 2, image_height, 'Title', Align=0.5, /Device
Add a bit to the height to move the title up off the top of the image.
Also add Charsize keyword to make the title bigger.
etc...
