Code below will rename all files so that they can be found in order:

f=file_search('img_*.tif', count=n)
max=20000 ;<--- this should be larger than your max
nzeros = ceil(alog10(max)) > 0
myformat = '(i0'+strcompress(nzeros, /re)+')'

for i=0L,n-1 do print, f[i],' -> ', 'img_'+string((strsplit(file_basename(f[i], '.tif'), '_', /ex))[1], format = myformat)+'.tif'

If you like the above, run it like so:

for i=0L,n-1 do file_move, f[i], 'img_'+string((strsplit(file_basename(f[i], '.tif'), '_', /ex))[1], format = myformat)+'.tif'
