hi,

in a file index_html, I search to have the height of a image, but this, is in a subdirectroy called "images"

After a request of a database, I have the name of the image in a variable "nom"

if I write

< dtml-var expr='images.'+nom+'.height' > the result is

images.x0y0.height

(x0y0 is the name of my image,)

if I write

< dtml-var expr='images.x0y0.height' > the result is

275

ok, it's the height of my image

how to make to have the first sentence, but with the result is "275" ?
