Magento how to display a block with a small image over the actual product image by using product id -

-

i have table contain product ids , small images. need display image on actual product image. how can display small image in every place product image appeared, is: product view, related product, list, grid.. without changing there template.

is there programmatic way display small image everywhere without need change in every template product image display.

yes quite possible. not easy though.

there helper that

mage_catalog_helper_image

within helper extend init function , rewrite assignment of watermark. enable in backend in system > configuration > design > watermark. use helper init function assign additional image have.

when finished, make sure clean cache , image cache. otherwise images not generated.

it still possible images wont have additional image overlay. more of template issue doesn't use helper function.

(i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
